Determination of cell constants

As in PVC Thermomat measurements only the alterations in the con-

ductivity are measured and evaluated, the cell constants of the con-

ductivity cells used in the PVC Thermomat, which are normally in the

range

1.00...1.20

, only need to be entered exactly if the absolute value

for the conductivity is to be shown correctly. The exact entry is also re-

quired before carrying out the GLP test for conductivity. The cell con-

stants can either be entered manually or determined automatically with

the aid of a defined standard solution.
